Water drain switching device

Abstract

The present invention discloses a drain switching mechanism which includes a switching box placed between a water tray with a drip open and a water tank, the switching box having an external exhausting region with opening at the top and a drainage system communicated with the external exhausting region and extending to outer of the organism, the condition is a internal drainage condition when water fall into the water tanks from the drip open, one of the switch box and the water tray is set oppositely to the organism for switching between the water drain condition and the internal drainage condition. The present invention provides a water drain switching mechanism, which can used in the machinery with in and out water drain demand, can switch the water drain modus in the machine and the water drain modus out of the machine instantly, and has fast response speed, convenient usage.

Description

technical field [0001] The present invention relates to a drainage structure, in particular to a drainage switching device capable of switching between an internal drainage mode and an external continuous drainage mode of a dehumidifier, an air conditioner, and the like. Background technique [0002] see figure 1 As shown, there are two types of draining structures for existing dehumidifiers: one is the internal draining mode, so that the drip port 11 of the water receiving tray 12 is facing the water tank 26 inside the machine below it, and the water is discharged into the water tank 26, After the water tank 26 is full, the water is poured out. This internal drainage method is suitable for short-term dehumidification; the external continuous drainage method, the main structure is to set a connection port 3 on the side wall of the water tank 26. The connection port 3 is configured There is a sealing plug cover 31. When continuous drainage outside the machine is not required...

AI Technical Summary

Problems solved by technology

[0004] 1. The above two drainage methods are usually used alone, and the two are not in a standby state at the same time, especially when draining inside the machine, the drain pipes required for the drainage outside the machine are idle, and when the drainage outside the machine is required , it is necessary to open the cover to connect the drain pipe, the switching operation is cumbersome, and it cannot be switched arbitrarily, which is very inconvenient to use

[0005] 2. The drain pipe 32 is easily bent and blocked in the machine, affecting the drainage function, and even causing damage to the dehumidifier in severe cases

[0006] 3. When switching from the internal drainage mode to the external drainage mode, only when the accumulated water in the water tank 26 exceeds the liquid level where the connection port 3 is located, can the water in the water tank 26 overflow into the drain pipe 32 to realize machine drainage. External drainage, there is obvious lag in switching, and it cannot be replaced immediately, which is inconvenient to use, and some stagnant water will always accumulate in the water tank 26, which is easy to breed bacteria and has unsatisfactory hygienic performance

[0008] Although this solution solves the problem that the drain pipe is easily bent and blocked in the machine and affects the drainage function, and further has the advantage that the port of the conduit 14 is located outside the machine so that it is relatively convenient to switch and connect the drain pipe, but this solution also has the same problem in the machine. Drainage and external drainage are used separately and are not in a standby state at the same time. It is still impossible to switch instantly anytime and anywhere, especially when switching from external drainage to internal drainage, it takes a long time to let the dripping Only when the water fills the conduit 14 and overflows from the flange portion 22 can it really switch from the external drainage to the internal drainage. There is an obvious lag in the switching, and it cannot be replaced and used immediately, which is inconvenient to use; and on the water tray 12 There will always be some stagnant water in the space between the conduit 14 and the flange 22, which is easy to breed bacteria and has unsatisfactory hygienic performance.
